Impact of Highly Saturated versus Unsaturated Fat Intake on Carbohydrate Metabolism and Vascular Reactivity in Rat

Figure 5

Effect of tempol on the contractile response to Phe. (a) Concentration–response curves to phenylephrine (0.01–100 µM) in aortic rings from control, olive oil, palm olein and lard diets in absence and in presence of tempol (100 µmol/L). (b) Histogram represents the difference in area under curve between contractions with and without tempol for each group expressed as percentage of Phe effect. Results were expressed as mean values ± SD, n = 7-8 animals per group. The limit of statistical significance was set at . Histogram bars with different letters (a, b, c) are significantly different. AUC: area under the curve.
